I was referring to this current round of sabre rattling, but if you're referring to the JCPOA, I should inform you that Iran agreed to monitoring and verification, not only under strictly restricted grounds. The deal did not give inspectors the right to freely roam. Access to military sites remained contentious and largely off limits. Iran never gave access to Parchin, for example. This meant Iran was free to continue their nuclear weapons development program - though of course in secret.
Further, the JCPOA unlocked $100B in frozen assets which the brutal dictator Ayatollah Khamenei immediately stole and used to cement his position of power. The JCPOA also lifted oil sanctions which further enriched Khamenei to the tune of $10-30B per year.
The JCPOA was commonly regarded as impotent and symbolic at best, and quite harmful at worst.

They both meant it. This is a crucial fact from the cold war. The world really was minutes away from nuclear war. I highly recommend reading the account of Stanislav Petrov [https://en.wikipedia.org/wiki/Stanislav_Petrov], a Russian lieutenant colonel, who in 1983 narrowly avoided nuclear war by heroically refusing to report an apparent missile launch by the U.S. During this period the U.S. formally developed the Mutually Assured Destruction doctrine which automated nuclear launches in the event that no one was left alive to retaliate.
You use an example of two deadly serious adversaries willing to destroy the world as an example of something we should not fear?
